Divid 128 repeatedly by the smallest prime numbers you can find until you get to 1. Like this:
128 / 2
64 / 2
32 / 2
16 / 2
8 / 2
4 / 2
2 / 2
You can see from this that the only prime factor of 128 is 2
128/2 = 64
64/2 = 32
32/2 = 16
16/2 = 8
8/2 = 4
4/2 = 2
2/2 = 1
128 = 27
1, 2, 4, 8, 16, 32, 64, 128
Just make a T graph
1 .... 128
2 .... 64
3 .... none
4 .... 32
etc.
Good Luck!
1,280 = 28 x 5
128 = 27
128 = 27
The only prime factor of 128 is 2 because 2 x 2 x 2 x 2 x 2 x 2 x 2 = 128
Their product.

2048/128 = number of chips.
The GCF of 158 and 256 is 2. This leaves 79 and 128 remainder after division respectively. There is actually no other common factor aside from 1 between them as 79 is prime and doesn't go into 128.
It is 2 and as a product of its prime numbers in exponents 2^7 = 128
2x2x2x2x2x2x2=128 27 = 128
As a product of its prime factors in exponents: 2^7 = 128
The only prime number (factor) of 128 is 2.
The only even prime number is 2.
It is a composite number.
Its prime factor is 2 and as a product of its prime factor 2 to the power of 7 = 128

128 is a composite number. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.
Prime factorization is breaking down a number into all of the prime numbers that make it up.For example, in 128, since it is even, the easiest first step would be diving by two, a prime number.64 * 2 = 128. Now divide 64, another even number, by two.32 * 2 * 2 = 128. Divide 32 by two.16 * 2 * 2 * 2 = 128. Divide by two again.8 * 2 * 2 * 2 * 2 = 128. Divide by two again.4 * 2 * 2 * 2 * 2 * 2 = 128. Divide by two a final time.2 * 2 * 2 * 2 * 2 * 2 * 2 = 128. This is your prime factorization.But you write it condensed, so 27 would be the prime factorization for 128.
2^7
128 is composite because you can divide it by 1,2,4,32,64,128128 is a composite number because it is an even number and therefore has 2 as one of its factors. A prime number has exactly 2 factors, 1 and itself.
